the future of zmodem is async as I refined zmodem2 API as follows:

1. ZmodemSession holds the protocol state.
2. ZmodemEvent provides the interface for consuming next events.

I.e. it is to bind to the future (while being still decoupled from them). Also next version of protocol will be zero deps and can compile with rustc only.

#zmodem #rust

tpm2_protocol 0.6.1

0.6.0 and 0.6.1 are really the same, i just fucked up tpm2sh 0.6.0 so...

OK, learning Rust as I got but I was still missing Any implementation so here it is:

https://github.com/puavo-org/tpm2_library/commit/5066da1e529c2c6fc3667ae1e4f2be397836684b

This is a milestone commit given that the implementation is capable of empowering driver, which is a consequence of being able to dynamically interpret the protocol byte stream. I.e. starting from this commit ID it would it driver implementation ready.

It is proven by the test that builds a 100 element list of random objects, streams the list and parses from stream another list, and finally compares that the lists have equal amount of element and each element matches each other.

The test is here:

@Aissen I was looking for something where I get some robustness but fine-tune the cli usage for tpm2sh :-) It does the job for me.

My favorite command-line parser for Rust:

https://github.com/blyxxyz/lexopt

I.e. it does not create command-line for you and you can fully control of the user experience.

and if done correctly it improves security properties of any tool as the input layer is always an attack vector.

I mean cli is a gui of one form and usuall guis are not sprayed to the source code

In some cases this could be the early phase also for new kernel code given that you can quite easily make parts of the code context independent, and by being part of kselftest it would get some stress testing before it is part of the actual kernel code.

I wonder if it either is or could be allowed kselftest to be written in Rust assuming that it requires only rustc and has at most std dependencies? Not talking a cargo build here.

Procedural macros in Rust:

- How to use them with plain rustc?
- Why they need to be in a lib crate?

The most important setting in fish shell:

set -g fish_autosuggestion_enabled 0

Fucking worst default in a shell that anyone has ever put to any shell (unless you are going epileptic seizure)

My tpm2_protocol crate could be useful also for e.g. some scenarios where you to format your crypto proofs in TPM2 structures wi/o having TPM.

Great, I've used before external crate for this:
https://doc.rust-lang.org/beta/std/io/trait.IsTerminal.html

Apparently std has had this for over two years already.

@pinkforest I noticed that more i bake the implementation into syntax tree macros, the more i actually appreciate super static text editor like (plain) vim. Anything that auto-completes gets in the way as you sort of define how things complete automatically with a manual script :-)

i.e.

1. better coverage
2. time saved from writing tests
3. less dependecies
